LAR2G331MELB35

The LAR2G331MELB35 is an aluminum electrolytic capacitor in a snap‑in terminal (radial can) package, rated at 330 µF and 400 V with ±20% tolerance. It is specified for general-purpose applications that require high ripple endurance and elevated temperature operation.

Designed to withstand demanding ripple conditions, this capacitor supports continuous operation at 105°C and includes design features to reduce short incidence under overvoltage conditions, while meeting RoHS requirements.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance rated at 400 V with −20%/+20% tolerance (measured at 120 Hz, 20°C).
• High-temperature endurance — Specified to withstand 2000 hours of rated ripple current at 105°C, supporting prolonged operation in elevated-temperature environments.
• Overvoltage safety behavior — Designed to reduce short incidence when subjected to overvoltage (rated voltage × 1.5), improving robustness under transient or fault conditions.
• Ripple current capability — Rated ripple current: 1.44 A at 120 Hz and 2.059 A at 100 kHz; frequency-dependent coefficients increase allowable ripple at higher frequencies.
• Operating temperature range — −25°C to +105°C, consistent with 400 V/450 V variants in the series.
• Mounting & package — Snap‑in terminal, radial can package for secure through‑hole board retention.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supplies — Use where a 400 V, 330 µF snap‑in electrolytic is required for bulk energy storage or smoothing in general-purpose power supply designs.
• General-purpose power electronics — Applicable in circuits that demand sustained ripple performance and elevated temperature endurance.
• Industrial equipment — Suitable for through‑hole assemblies needing a robust, high‑voltage electrolytic capacitor with snap‑in mounting.

Unique Advantages

• Long-term ripple endurance: 2000‑hour rated ripple current endurance at 105°C helps maintain capacitance and reliability over extended high-temperature use.
• Improved overvoltage behavior: Built to reduce incidence of shorts under 1.5× rated voltage conditions, aiding safety during abnormal line events.
• Designed for higher-frequency operation: Ripple current ratings and frequency-dependent coefficients provide increased allowable ripple at higher frequencies (demonstrated by the 100 kHz rating).
• Reliable board retention: Snap‑in radial can package simplifies placement in through‑hole power assemblies and secures the component mechanically.
• Regulatory compliance: RoHS directive compliance supports use in regions requiring restricted substances conformance.
